Empty ext3 filesystem after swap starvation
Hi there,
Using Sid, I recently did an aptitude upgrade which went into a crazy
dependency resolving process (maybe because of squeeze being released
and me not doing a full-upgrade). It ate all of my 1.5go of ram, then
started eating my 2go of swap. By the time I had only 50mo of ram left
(cached) and no swap left, I finally took a step by ctrl-c-ing aptitude
which was still working (around 200 000 packages had been examined).
The day after, a quick cd into my data partition failed... everything
was gone. Simply and purely gone. e2fsck says the fs is clean, forcing
him to do a scan only resulted in a "lost+found is missing, would you
like to create it?" (I must say I answered yes, this was dumb).
Well, has anyone heard of an entire ext3 fs becoming blank?
It seems the fs tree was corrupted at its root somehow, but I know my
files are still there. Photorec and Foremost gave some results by the way.
Here is my setup :
Device Boot Start End Blocks Id System
/dev/sda1 1 261 2096451 82 Linux swap / Solaris
/dev/sda2 262 1044 6289447+ 83 Linux
/dev/sda3 1045 6266 41945715 83 Linux
/dev/sda4 6267 30401 193864387+ 83 Linux
/dev/sda2 on / type ext3 (rw,errors=remount-ro)
/dev/sda3 on /home type ext3 (rw)
/dev/sda4 empty (no longer mounted, was ext3 on /share)
localhost:~# e2fsck /dev/sda4
e2fsck 1.41.12 (17-May-2010)
/dev/sda4: clean, 11/12124160 files, 808899/48466096 blocks
Cheers,
Ben
(i did not rm -rf while asleep right?)
